Özet
Bu çalışmada, yaşlı ceviz ağacının yumuşak odun ve odun çeliklerinden elde edilen metanolik ekstraktların, mung fasulyesi (Vigna radiata) ç eliklerinin k öklenmesi üzerine etkisi incelenmiştir. Her iki çelik tipinde de kromatogramlarm Rf l .0 bandında önemli düzeyde uyarıcı aktivite saptanmıştır. Ortamda oksin (IBA) bulunması durumunda, özellikle odun çeliklerinin spesifik Rf bandında sinerjistik etki gözlenmiştir. İki yönlü kağıt kromatografisi sonucunda, Rf bantlarmdaki kofaktör aktivitesinden birden fazla fenolik maddenin sorumlu olabileceği sonucuna varılmıştır. Ancak, çelik tipleri arasında fenolik madde kompozisyonu ve oransal miktarı açısından, genelde belirgin farklılık saptanamamıştır.
In this study, the effect of methanolic extracts obtained from softwood and hardwood cuttings of mature walnut, on the rooting of mung bean (Vigna radiata) cuttings were examined. Significant promotive activity was predicted on Rf 1.0 zones of choromatograms in both types of" cuttings. At the presence of auxin (ISA), synergistic effect was observed especially at the specific Rf zone of hardwood cuttings. As a result of two dimensional paper chromatography, more than one phenolic compounds may be responsible from the cofactor activity at Rf zones was concluded. However, no marked differences generally predicted among the cutting types in relation with the composition and relative amounts of phenolic compounds.
